Description
- The present invention is related to a locking apparatus meeting the regulation of U.S. customs, and more particularly to a locking apparatus with both numeral wheel locking unit and key-drivable locking unit.
- The conventional locking apparatuses include numeral locks, press key type locks and key-driven locks. These locking apparatuses are widely applied to various fields. For example, Taiwanese Patent Nos. 32470 and 46563 and Publication Nos. 498918 and 369068 respectively disclose numeral locks and key-driven locks applicable to baggage case or suitcase.
- Practically, it is known that when checked by U.S. customs workers, in case it is found the customs workers that the contents of the baggage case or suitcase are suspicious, the customs workers are authorized by U.S. government to forcedly break off the lock of the baggage case or suitcase and open the same for checking the contents. The damaged lock will be a loss of a user and will lead to trouble and inconvenience to the user, especially during travel.
- In order to improve the above situation, U.S. government and customs regulate that the lock manufacturers must provide a standard key for the customs for opening all the locks manufactured by the manufacturers. According to this regulation, there are six lock manufacturers all over the world (including two manufacturers in Taiwan) are allowed to manufacture such locks. The applicant is one of the two manufacturer in Taiwan. When meeting the above regulation, some issues must be considered in designing and manufacturing such locks. For example, it is considered how to combine the numeral wheel locking unit and key-driven locking unit in the locking apparatus to together control the lock hook thereof without affecting or interfering with the original operation and function of the locking apparatus. Also, the manufacturers must consider the cooperation of the two locking units and the state of one of the locking units when the other is operated. These issues are not discussed in the above Patents.
- It is therefore a primary object of the present invention to provide a locking apparatus with double locking units. The locking apparatus includes a numeral wheel locking unit and a key-drivable controlling unit for together detaining a lock hook or rod member. When the numeral wheel locking unit or the key-drivable controlling unit is unlocked, one end of the lock hook or rod member can be rotated or moved.
- According to the above object, the locking apparatus of the present invention includes a housing defining a cavity, a locking unit and a controlling unit mounted in the cavity and a lock hook or rod member. When the numeral wheels are turned to a set number, the lock core is permitted to freely axially move. The lock hook or rod member has a fixed end connected with a lock core of the locking unit and a free end which is detained by the controlling unit in a locked state and rotatable or movable in an unlocked state.
- The controlling unit includes a rotary section in which a key can be inserted and a reactor and a driven unit disposed on the rotary section for detaining the free end of the lock hook or rod member in the locked state. The reactor and the driven unit are movable with the key to release or detain the free end of the lock hook or rod member.

FIGS. 1 and 2 . The present invention includes ahousing 10 defining acavity 11. A numeralwheel locking unit 20 and a key-drivable controllingunit 30 are respectively mounted in two sides of thecavity 11. In a preferred embodiment, the numeralwheel locking unit 20 is a standard numeral lock model which includes multiplenumeral wheels 21 and alock core 22 combined therewith. Eachnumeral wheel 21 partially protrudes from thehousing 10 for a user to turn. When thenumeral wheels 21 are turned to a set number, thelock core 22 is permitted to freely axially move as shown inFIG. 3 . (This pertains to prior art and will not be further described hereinafter.) - A fixed
end 24 of a lock hook orrod member 23 is connected with the head section of thelock core 22. The lock hook orrod member 23 is movable along with thelock core 22. The lock hook orrod member 23 has afree end 25 opposite to the fixedend 24. Thefree end 25 can be detained or released by the controllingunit 30. - In the first embodiment of the present invention as shown in
FIGS. 1 and 2 , the controllingunit 30 includes arotary section 31. Akey 40 can be inserted into therotary section 31 to drive and rotate therotary section 31. Areactor 32 is mounted on upper side of therotary section 31 and connected with a drivenunit 33. The drivenunit 33 outward protrudes from thehousing 10. Thereactor 32 and the drivenunit 33 are rotatable along with therotary section 31. The drivenunit 33 is formed with anotch 34 having anopening 35. Thefree end 25 of the lock hook orrod member 23 is coaxially detained in thenotch 34.FIG. 2A shows that theopening 35 faces thefixed end 24 of the lock hook orrod member 23 and blocked by aridge section 12 of thehousing 10. Under such circumstance, thefree end 25 of the lock hook orrod member 23 cannot leave thenotch 34. Alternatively, theopening 35 can be directed in reverse to the direction as shown inFIG. 2A to achieve the same effect. - Referring to
FIG. 3 , when thenumeral wheels 21 are turned to a set number, thelock core 22 is permitted to freely axially move, whereby the lock hook orrod member 23 can be moved upward. At this time, thefree end 25 of the lock hook orrod member 23 can leave thenotch 34 of the drivenunit 33 to form an unlocked state. -
FIG. 2 shows the locked state of the present invention. When a key 40 is inserted into therotary section 31 of the controllingunit 30 in a direction as shown by the arrow ofFIG. 4 , therotary section 31 can be rotated along with the key 40. At this time, thereactor 32 and the drivenunit 33 can be moved along with therotary section 31. In a preferred embodiment, the angular displacement of the drivenunit 33 is set smaller than or equal to 90 degrees. Accordingly, theopening 35 of the notch of the drivenunit 33 can be turned to a position as shown inFIG. 4A to release thefree end 25 of the lock hook orrod member 23. At this time, thefree end 25 of the lock hook orrod member 23 can be turned through theopening 35 out of thenotch 34 of the drivenunit 33 to form an unlocked state. -
FIG. 4 shows the position of thefixed end 24 of the lock hook orrod member 23. In comparison with the position of thefixed end 24 in the unlocked state as shown inFIG. 3 , thefixed end 24 is positioned at a lowest point in the locked state as shown inFIG. 2 . Therefore, although thenumeral wheels 21 of the lockingunit 20 are not turned to the set unlocking number, a customs worker can use a standard key 40 to drive the controllingunit 30 and release thefree end 25 of the lock hook orrod member 23 from detention. -
FIGS. 5 and 5 A show a second embodiment of the present invention, in which the structure of the controlling unit is modified and denoted byreference numeral 50. The controllingunit 50 includes arotary section 51 in which a key 40 can be inserted. A head end of therotary section 51 has a curved slope or amale spiral section 55. Areactor 52 is mounted on upper side of therotary section 51 and connected with a drivenunit 53. The drivenunit 53 outward protrudes from thehousing 10. The drivenunit 53 is formed with anotch 54. Thefree end 25 of the lock hook orrod member 23 is coaxially detained in thenotch 54. In this embodiment, thereactor 52 has a curved slope orfemale spiral section 56 formed inside thereactor 52. At least a part of the curved slope orfemale spiral section 56 contacts with or engages with the curved slope ormale spiral section 55 of therotary section 51. -
FIG. 6 shows that when thenumeral wheels 21 are turned to a set number, thelock core 22 is permitted to axially move, whereby the lock hook orrod member 23 can be moved upward. At this time, thefree end 25 of the lock hook orrod member 23 can leave thenotch 54 of the drivenunit 53 to form an unlocked state. In a preferred embodiment, aspring 57 is disposed between thereactor 52 and the drivenunit 53 for restoring thereactor 52 and the drivenunit 53 to their home positions and stabilizing the movement thereof. -
FIG. 5 shows the locked state of this embodiment of the present invention. When a key 40 is inserted into therotary section 51 of the controllingunit 50 in a direction as shown by the arrow ofFIG. 7 , therotary section 51 can be rotated along with the key 40. The curved slope ormale spiral section 55 of therotary section 51 contacts with or engages with the curved slope orfemale spiral section 56 of thereactor 52. Therefore, when therotary section 51 is turned with thekey 4, the contacting portions of the curved slopes or spiral sections of thereactor 52 and therotary section 51 are forcedly enlarged. Accordingly, the drivenunit 53 is driven to axially downward move. At this time, thenotch 54 leaves thefree end 25 of the lock hook orrod member 23 as shown inFIG. 7 and thefree end 25 can be freely rotated. It should be noted that when the key 40 is turned, by means of the engaged curved slopes or male andfemale spiral sections reactor 52 and the drivenunit 53 are forced by therotary section 51 to axially move. -
FIG. 8 shows a third embodiment of the present invention, in which the structure of the controlling unit is modified and denoted byreference numeral 60. The controllingunit 60 includes arotary section 61 in which a key 40 can be inserted. A head end of therotary section 61 has aswitch 65. In this embodiment, theswitch 65 is a semicylindrical body as shown inFIG. 8A . Areactor 62 is mounted on upper side of therotary section 61 and connected with a drivenunit 63. The drivenunit 63 is formed with adent 64 having an opening. The opening of thedent 64 faces thefixed end 24 of the lock hook orrod member 23. The drivenunit 63 and theridge section 12 of thehousing 10 together detain thefree end 25 of the lock hook orrod member 23 as shown inFIG. 8B . - The lower end of the
reactor 62 is formed with a key 66 corresponding to theswitch 65 of the rotary section. Thereactor 62 has aspring 67 which always exerts an outward swinging force onto the drivenunit 63 disposed on thereactor 62.FIG. 8A shows that the key 66 is a substantially quarter-cylindrical body which is at least partially stopped by theswitch 65 of therotary section 61. That is, thespring 67 always exerts a force onto the drivenunit 63 disposed on thereactor 62, making the drivenunit 63 tend to swing to outer side of thehousing 10. Relatively, thespring 67 makes the key 66 on lower side of thereactor 62 tend to swing to inner side of thehousing 10. However, theswitch 65 stops the key 66 from swinging to the inner side of thehousing 10. - Referring to
FIG. 9 , when thenumeral wheels 21 are turned to a set number, thelock core 22 is permitted to freely axially move, whereby the lock hook orrod member 23 can be moved upward. At this time, thefree end 25 of the lock hook orrod member 23 can leave thedent 64 of the drivenunit 63 to form an unlocked state. -
FIG. 8 shows the locked state of this embodiment of the present invention. When a key 40 is inserted into therotary section 61 of the controllingunit 60 in a direction as shown by the arrow ofFIG. 10 , therotary section 61 can be rotated along with the key 40.
